0 Application. filed April 4,

2T0 all 'w-lwmc't may concern 1 Be it known that I, JOHN T. DALCHER, a citizen of the United States of America, and a resident of Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Oil-Burners for Stoves, Furnaces,

&c., of which the following is a specification.

his invention relates 'to' oil burners adapted for use in stoves, furnaces, and the like and-is an improvement on another inand described in, U. S. Letters Patent No. 1,281,301 issued .to me Sept. 12,1918.

, The object of the present invention is-the production of a device of this character which will be simple in construction, efl'ect ve in operation, and-efficient in fuel con sumption. V y

The invention consists primarily in a tubular memben forming a mixing chamber and surrounded by an oil pan above which is a hood adjustabletoward and from said 7 further consists in. certain construction and arrangeparts 'which will be understood reference to the description of the and to the claims to be hereinafter The invention results although it. is to be understoodthat the various instrumentalities of which the invention consists'can be v'ariously arranged h and organized and th e inventlon is not limited to the precise arrangement and or ganization' of these ms'trumentalities as herein shown and describedexcept as re-- quired by the scope of the appended claims.

This tubular member 10 is supported by and preferably threaded to an elbow pipe fitting 12 having a tubular boss 13 through which extends an oil supply pipe 14.

The outer end of the boss 13 has threaded thereto a nut 15 between which and the end p'f'said boss is a packing member 16 which prevents the leakage between said pipeand the inner wall of the cylindrical hole through the boss 13. V The tubular member two annular shoulders 17 and 18 on the 'inner face thereof, these shoulders, beingv spaced apart as indicated in F ig. 2 of the drawing e On the lower shoulder 18 is supported a cone-shaped annular air diffuser 19 and in a similar manner another cone-shaped annular'air difi'user 20 is supported upon the upper shoulder 17. J

ear the pcripherywf the annular air diffuser '20 are *a plurality of drain holes 21 through which the 011 that does not vaporize may'pass downwardly into the chamber 22 and through. drain holes 23 in the tubular, member 10 into the pan 11. The upper face of the pan 11 is provided with. a plurality of annular ribs 24, the .height of which is less than the peripheral flange 25 of said pan.

10 is provided with I Extending from the pan 11 is anoyerflow pipe 26.

The upper end of the oil supply pipe 14 has threaded thereto the oil distributer 27 aving a central passage 28 therein communicating at its upper end with a plurality of discharge outlets 29. Near the lower end of the air distributer 27, said distributer has mounted thereon a cone-sha ed air diffusing liich extends overwthe upper en of t e annular air diffuser 19. This air-difl'usin ring 30 is intermediate the annular air di users 19 and 20 as indi- 1 fcated in Fig. 2 of the drawings. Fig.2 represents'a vertical sectionof same on.line,2, 2, on

Between the air diffusing ring 30 and the ring 30 the peri h-' discharge outlets 29, the oil distributer 27 a plurality of sharp pe rovided with 'pheral projections 3 1over'which the oil discharged fromthe outlets 29 is adapted to flow. I [Theupper end of the oil distributer -27 is provided with" a threaded shank 32 on WlllCh is adjustably mounted a hood 33 havt the oil pair 11 thereby varying the size of the annular discharge passage 37 from the ing on its under face an annular flange 34,.

the under face 35 of which is inclined downwardly and outwardly.

This flange 34 1s immed'ately above the tubular member 10, the face 36 ofthe upper-.- end of which is inclined downwardly and outwardly.

By turning the hood 33 on the shank 32, the hood 33 may be moved towardand from mixing chamber.

This hood 33 is provided with a cone-.

shaped apron 38 inclined downwardly and outwardly toward the pan 1-0, the lower end 39 of which is immediately above the outer rib 24.

It is obvious, therefore, that when the hood 33 is adjusted toward" and from the oil pan 11, the space between the outer rib 24 and the "end 39 of the hood 33 will be varied in size. 1

- When the-hood is adjusted relatively 'to the oil distributer 27, it is locked in adthreadedupper end of the oil. supply" pig e 14. i

The upper end of' the shank 32 is prooil distributer27 may be screwed onto the he tubular member 10 may be supported entirely uponthe pipe fitting 12 or the pan 11 may be supported in any other manner as desired, Y

Metal washer 16 is firmly securedto oil supply pipe 14 and when pressed against lower face of boss 13 by means of cap or nut 15, secures pipe 14 in its proper post tion.

The discharge outlets 29 may belhori-l zontal as indicated in the drawmgs or inv clined downwardly" and outwardly as desired. v

The drain holes 21 and 23'are provided to take care of such fuel as is not properly vaporized in the-mixing chamber.

The overflow pipe leads to a drain tank and takes care of the fuel inthe oil pan In the operation of the device, air'at moderate draftis supplied through the pi e fittin 1'2. and as this air is admitted to t e cham er, 22 its velocity and direction of flow is controlled by the annular air diffusing members 19 and 20 and the air diffusing-- ring- 30 intermediate said diffusers 19 and'20. I b

When alimited supplied through e on pipe 14 and per.-

' mitted to flow into theoil panr11, through 1 the discharge outlets 19 and allowed to flow down the upper surface of. the ring 30 onto the annular diffusing member 19 and which the qliliantity of fuel has been t through the holes 23 ,into the pan 11, the

device is ready for use. 7 The oil supply 's then cut off and the fuel in the oil pan 11 is ignited,"

The. heat from the burning quickly transmits heat tosaid pan 11, the hood 33, :and chamber 22.

, When. these parts 'oil in thefpan 2w are sufiiciently heated,

all of the parts within the the fuel and air isadmitted-to the chamber' 22 through the oil supply pipe 14 and p gs he fuel-oil is preferably supplied to the 7 ,pipe 14 from. a gravity tanli from which the oil flows to the burner by gravity.

As this tank forms no part of the present invention, it is deemed unnecessary to show the same in the drawings as aotank of any usual construction may be used for this purpose.

-- As the fuel-oil into the oildistri uter 27 and through the discharge outlets 29 therefrom, said 011 will flow over the sharp peripheral projections 31 downwardly onto the air diffusing ri1 1lg30. i. his fuelas it passes from thedischarge asses through the pipe 14 outlets 29 has become thoroughly heated owing to the heatedcondition of the'various parts of thedevice due to the ignition of the oil in the pan 11.

- The air which is admitted through the pipe 12 is discharged through the annular air diffuser 19 and its velocity is considerabl increased dueto the con'e-sha e of said di user 19, the upper end of whic forms a the discharge outlets 29.

ected with increased velocity the surface of this oil dis- The hot oil is'thereb broken up and car- .ried into the mixing c amber.42.

In the mixing chamber 42'the oil 'and air is further heated and thoroughly atomized and then discharged into the outer mixing chamber through the circular opening 37. The face 35 of the flan e 34 surrounding the mixingchamber,42. as a greater inclination'than the coacting face 36 of the upper end of thejtubular member '10 Tand consequently the velocity of the heated mixture is increased as it passes outwardly through the annular passage 37 and strikes .the hot' walls of the outer chamberbetween the cone-shaped a ron 38 and the oil pan It is obvious vt erefore that in' the present-device any necessary adjustments may be made according to 'the specific amount been of fuel being usedvby' simply adjusting the hood 33 toward and from the oil pan 1.1.

Any of the fuel which is not properly vaporized may pass directly into the outer mixing chamber through the drain holes 21 and 23 without The provision of a number of circular ribs 24 provides a means for still further vaporizing the 'fuel which passes into the outer mixirig chamber without having previously ormed into a perfect gas.

This makes a very simple and effective oil burner for furnaces, stoves, and the like which'may be constructed at a minimum expense and may be easily installed.

It is believed that the operation and many advantages of the invention will be understood without further description.
